Tritech Gemini 720is Real-Time Multibeam Imaging Sonar
The Tritech Gemini 720is available with a 1000m or 4000m depth rating provides users with real-time, crisp imagery for applications including obstacle avoidance, target detection and close-range inspection. With a 120-degree field of view (10 degree tilt) and a fast update rate of 30Hz, the Gemini 720is sonar is ideal for poor visibility environments. Gemini 720is features a 720kHz operating frequency and an integrated sound velocity sensor to assist in providing the sharpest image possible, with accurate ranging. Redesigned for ease of install onto a variety of ROVs, AUVs and other underwater platforms, the Gemini 720is operates through Ethernet or VDSL communications.
The compact size of the Gemini 720is allows for versatile deployment, including pole-mount assembly (customer-supplied). It is designed for easy installation onto various ROVs, AUVs, and other underwater platforms, supporting both Ethernet and VSDL communications. The standalone Genesis software package offers users a tailored control and display interface, featuring click-and-track functionality and engineering measurement tools.
